connect your stuff to this filter and the polarity is always
correct and can be referenced to the circuit ground.

It would be easier to put a large sign below the control computer's screen, and

I think in addition to the message box in the g-code file I will add a
HAL message component that will trigger off a one shot component that is
connected to the machine on state. This way each time the machine is
turned on the pop up message will show up to remind the user to connect

If you want to keep using the ground clamp as is I'd order two sets
of parts from John... :-) You won't need them next week or two weeks
from now.. Just as soon as the memory of this fades a bit.
Also, you will find out that how you put the clamp on the table will
affect the plasma flam

One suggestion is to run an EXTRA ground cable from the
plasma power supply to the machine table. Not the base of
the frame, but the actual table the work sits on, if that
moves. This

Put a permanent bolt-on lug in the _middle_ of the ground lead then.

John,
In this situation the plasma cutter unit is used on the CNC machine as
well as as a manual hand cutter. So the clamp remains to be universal.
It is trivial to switch between use on the CNC table or as a manual hand
cutter, as long as you don't forget the ground clamp.

To get a working usually involve exploring there others.
If ground clamp of plasma cutter must be checked every time problems could be
expected every now and then. It is possible to mitigate with proper procedures
as is done for air safety and it work most of the time although it cost money.

Les,
Thanks for the info. We were rethinking the machine grounding last
night. We will look into it further when we are putting it back together.
Thanks again,

Hi Jim,
There are a few precautions you can take so forgetting to clamp the
ground doesn't destroy your electronics. First use a star ground. Weld a
bolt to the frame of your machine and connect that to your supply mains
earth. Now make sure the mains earth for your computer and plasma cutter
I think I will use the following:

So my goal is to let others learn from my mistakes. So in that way I
tend to make a lot of them so everyone can benefit. Last night I was
working with the plasma machine and made a big one!
Don't ever forget to hook up the ground to the plasma cutter!
